Vehicular goodwill message system

Abstract

A method of communication between vehicle operators. The invention employs common display LEDs, the segments of which when appropriately turned on issue desired messages on the reader board for the operators of other vehicles. To issue a message the operator of a vehicle simply depresses a button on the control box, the operator of a vehicle behind sees the message for a length of time set by a monostable timmer.
